Sep 5, 2024 · Meniscal tears are the failure of the fibrocartilaginous menisci of the knee. There are several types and can occur in an acute or chronic setting. Meniscal tears are best evaluated with MRI.

Aug 30, 2024 · MRI grading system for abnormal high meniscal signal intensity was reported by Lotysch et al. Classification. Grade 1 to 3 have been described on MRI: grade 1: small focal area of hyperintensity, no extension to the articular surface. grade 2: linear areas of hyperintensity, no definite extension to the articular surface

Jun 12, 2024 · A horizontal meniscal tear, also known as a cleavage tear, is a type of meniscal tear in which the tear is oriented horizontally, parallel to the tibial plateau. These tears may be difficult to visualize on arthroscopy.

Jun 12, 2024 · Radial tears extend across the short axis of a meniscus perpendicularly to the tibial plateau and will extend in a radial orientation from the central intercondylar region. This is opposed to horizontal and vertical meniscus tears, which …

Jun 12, 2024 · Meniscal root tears are a type of meniscal tear in the knee where the tear extends to either the anterior or posterior meniscal root attachment to the central tibial plateau. They often tend to be radial tears extending into the meniscal root.

Jan 6, 2025 · Bucket-handle meniscal tears are a type of displaced vertical meniscal tear where the inner part is displaced centrally. They more commonly occur in the medial meniscus and are often associated with anterior cruciate ligament (ACL) tears .

Jun 12, 2024 · Complex meniscal tears extend in more than one plane, and can in turn create separate flaps of meniscus. Radiographic features MRI knee. The mensical tear usually includes a combination of radial, horizontal, and longitudinal components (any two or all three). Often the meniscus substance appears fragmented and tends to extend in more than one ...

A flipped meniscus is a sub-type of bucket handle tear where a large portion of meniscus flips to lie adjacent to the anterior horn leaving an empty space at the donor site. It implies either meniscocapsular / meniscopopliteal fascicle detachment or peripheral vertical longitudinal complete tear as was the case here.

Jun 12, 2024 · mri Ramp lesions appear as an abnormal signal at the peripheral most portion of the posterior horn of the medial meniscus. These lesions can be difficult to identify if there is little or no posterior meniscocapsular tissue separation.

Jan 4, 2022 · Meniscal extrusion can be assessed reliably on ultrasound and MRI 5 as well as on CT 7. Significant meniscal extrusion has been variably defined as ≥3 mm 1 or ≥4 mm 6 . References
